SAFETY FOR REPEATING GUNS Filed March 30, 1931 Patented ea. 22, 1931 FOB REPEATING GUNS Application filed March 30, 1931. Serial Ho. 528,241.

The purpose of my invention is to provide a safety structure of simple and economical construction adapted to automatically cooperate with the trigger of a repeating gun for normally causing it to be inoperative and adapted to be rendered inoperative upon subjecting the butt to pressure against the shoulder of the user.

A further purpose is to provide such a safety including a cap for the gun butt having limited hinged movement and a rod pivoted to the cap and slidably extended through the butt to position for cooperating with the trigger and arranging to function without in any way interfering with the action of the repeating mechanism.

It is my purpose in this connection to provide a safety of the kind mentioned and to provide an accurate guide forthe rod located near the trigger and formed by means of a single inserted strip in combination with standard parts of the gun frame.

With these and other objects in "view, my invention consists in the construction, arrangement and combination of the various parts of my safety for repeating guns, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which:

Figure 1 is a longitudinal, vertical, detail sectional view of a repeating gun equipped with a safety embodying my invention; and

Figure 2 is a detail, sectional view taken on the line 2-2 of Figure 1.

I have discovered that a very desirable safety for repeating shot guns can be made by providing the butt with a movable member and connecting therewith a suitable rod adapted to be moved to and from position for holding the trigger in non-discharging position.

One difliculty that has always existed heretofore with devices of this kind has been that they could not be used with a repeating shot gun because of the fact thatv in repeating guns a part of the shell handling mechanism is arranged to travel above the trigger toward the lfiutt of the gun into a recess provided there- As result of the structure just explained, no one heretofore, so far as I am aware has been able to install a safety of the kind now under consideration because proper space could not be found for the forward end of the trigger safety rod.

The problem may be more fully explained by reference to the drawings herewith in which the numeral 10 indicates generally the stock of the shot gun. At its forward end, on there is ordinarily secured to the stock, a frame indicated generally at A and having the ordinary trigger guard 11, in which is pivoted the trigger 12 with the upwardly projectin lug 13.

Extendlng rearwardly from the trigger guard is a frame part or plate 14 from which at the sides the guide members 15 project upwardly in parallel spaced relation.

At the rear end of the plate 14, the frame 7o extends upwardly as at 16 and thence forwardly again as at 17 What I have described is all of standard construction, except the lug 13 which may he welded to the trigger 12.

It will be observed that there is a substantial recess 18 above the trigger and projecting from it toward the butt of the gun.

The numeral 19 indicates the casing or frame for the repeating mechanism, which so includes the reciprocating part 20 adapted to travel into and out of the recess 18. As the member 20 slides rearwardly and forwardly it travels on the guides 15.

It will thus be seen that any safety which includes a rod running from the butt of the gun to the trigger must be so constructed and arranged as not to interfere with the recipro cation of the member 20. So far as I know, no one hitherto has been able to make a safety 9o device of the kind now under consideration which would work with a repeating gun and the reason for that has been the inability to construct and arrange the safety so as not to interfere with the function of the repeating mechanism.

I have provided-a safety which can be installed conveniently and readily on a shot gun of the type having a repeating mechanlsm.

I will now roceed to describe my im-' proved safety or regeatin guns.

I provide for the utt o the stock a suitable cap 21. A screw 22 is extended through the flange at the top as shown in Figure l and the cap fits loosely enough thereon to have limited pivotal movement. Extending through the stock of the gun is a bore 23 which is enlarged as at 24 near the butt.

On the inside of the cap 21 is an ear 25 to which is pivoted one end of the reciprocatin rod 26 as at 26. On the rod 26 near the pivot end is a washer or collar 28. Be-

tween the collar 27 and the forward end of the enlarged bore portion 24 a coil spring 29 is mounted on the rod 26. This spring nor-.

mally tends to hold the rod 26 and the cap 21 at what may be called the rearward limit of their movement.

The cap 21 is provided with a forwardly projecting tubular member 30, which may travel on the guide screw or the like 31. The screw 31 serves as a limit stop for the cap 21 when swung by the spring 29.

I also provide a yoke-like guard 32 hav ing its sides secured as indicated at 33 in dotted lines to the sides of the stock near the bottom and its central portion extending around the cap at the portion thereof far thest from the screw 22.

This guide 32 serves to limit the swinging movement of the cap 21, but more important serves to engage the ground or anything which might be struck with the gun to prevent accidental release of the safety.

The difficulty heretofore with a repeating mechanism gun has been to connect any safety rod with the trigger Without interfering with the reciprocating safety mechanism part 20. I have accomplished this connection in the following way:

Between the guides 15, I have inserted a small strip 34: and welded or otherwise secured it to the guides. The strip 34 does not project above the guides and into the recess 18 and therefore does not interfere with the repeating mechanism. The strip 34 has a central bore 35 in line with the bore 23 and with a hole 36 through the gun frame and slidably receives the forward end of the rod 26 in such way that when the parts are in normal position, the forward end of the rod 26 stands immediately above the lug 13 in position where it prevents pulling the trigger 12. When, however, the cap 21 is pressed snugly against the butt of the gun, the rod 26 will be moved forwardly slightly and until the notch 38 therein registers with the lug 13, so that the trigger can be pulled and the lug will project into this notch 38.

A. safety of this kind has a number of advantages.

It will be noted that it is automatic and does not depend upon any human element for belng moved to safety position. Yet when the butt of the gun is pressed firmly against the shoulder, the safety will be released for permitting the ordinaryuse of the gun.

With a'safety of this kind, there is no danger of accidents due to the failure of the user of the gun to set the safety either through forgetfulness or otherwise.

If by any chance, the cap 21 should be accidentally pressed to safety releasing position, it is obvious that as soon as the pres sure is removed, the spring 29 will automatically return the safety to on position.

I claim as my invention:

1. The combination with a gun having a repeating mechanism, part of which is adapted to reciprocate into the portion of the stock above the trigger and between it and the butt and having a trigger with a safety devicecomprising a rod slidably mounted in the butt and arranged below the path of travel of said reciprocating mechanism and adapted to move into and out of position for preventing operation of the trigger, a cap on the butt of said gun having slight pivotal movement, means for pivotally connecting the cap with said rod and yielding means tending to hold the rod in position for making the trigger inoperative.

2. In a structure of the class described, the combination of a gun having a stock with a trigger and a substantial recess above the trigger and between it and the butt, and a barrel with a repeating mechanism, part of which is adapted to reciprocate into said recess, with a safety comprising a cap having limited hinged movement on the butt, a rod pivoted on the cap and arranged to slide.

below said recess and out of the path of movement of the repeating mechanism into and out of trigger holding position.

3. In a structure of the class described, the combination of a gun having a mechanism adapted to reciprocate into and out of position above the trigger and between it and the butt and having at the forward end of the butt a frame including a trigger guard and a laterally spaced guide projecting rearwardly toward the butt therefrom with a safety comprising a cap having limited pivotal movement on the butt, a rod pivoted to the cap and arranged to slide below said recess and between said guides and out of the path of movement of the repeating mechanism into and out of trigger holding position, an insert between said guides and above said rod adapted to serve as a guide for the rod, and means for normally holding said rod in trigger holding position.

4. The combination with a gun having a repeating mechanism, part of which is adapted to reciprocate into the portion of the stock above the trigger and between it and the butt and having a trigger with a safety device comprising a rod slidably mounted in the butt and arranged below the path of travel of said reciprocating mechanism and adapted to move into and out of position for preventing operation of the trigger, a cap on the butt of said gun having slight pivotal movement, means for pivotally connecting the cap with said rod and yielding means tending to hold the rod in position for making the trigger inoperative, a guard on said stock extending around one end of said cap and projecting away from the butt beyond the cap.
